Even though free users outnumber paying subscribers by about three to one, the free tier generated only 9% of Spotify’s $1 billion-plus revenue last year; the rest came from subscription fees, according to a financial disclosure Spotify filed last month in Luxembourg.

The two tiers generate roughly the same amount of total listening in any given month, according to data shared with publishers. (Subscribers—who presumably want to get their money’s worth—tend to listen to a lot more music than free users.) In March, that amounted to over 4 billion streams each on Spotify Free and Spotify Premium in the U.S. alone, where online music companies have to share certain usage and royalty data with music publishers.

There’s quite a bit of fascinating math in the article, but it really boils down to those two paragraphs. Half of the songs played on Spotify result in just 9% of the revenue. That might sound a little crazy to you. This is the world’s most successful streaming music platform? Almost all the money comes from the streaming activity of a small number of users.

Well, compared to freemium games, that’s nothing. Last year, a report on monetization in mobile games found that the average freemium game makes half its revenue from 0.15% of all players. That’s not a typo. That’s a fraction of one percent providing half the revenue. Re/code’s Eric Johnson noted:

At a conference I attended last year, a representative of a gaming company — who declined to be named or interviewed for a story — claimed that his firm had worked with a Japanese game company with one player who spent about $10,000 per month on in-app purchases. The company, he said, had assigned an employee to cater just to that whale, to ensure that she was always satisfied with the game and therefore likely to keep coming back.

I’ve got it! Spotify just needs to introduce a $10,000 per month plan, for crazy rich folks. Bam. Problem solved. The world is saved, and Taylor Swift puts her music back on Spotify.

You know what’s lousy about the male gaze? Everything. This article in Aeon explores a fun new twist on conventional masculinity; the Captain America body:

But who is doing the fetishising? Not women. In 2000, The American Journal of Psychiatry published a telling experiment led by Pope at Harvard. College-aged men in Austria, France and the US were asked to choose both their ideal male body and the body they believed women preferred. In all three countries, men picked an ideal on average 28 lb (12.7 kg) more muscular than their own – and they believed that women wanted a male body 30 lb (13.6 kg) more muscular. The men consistently overestimated the appeal of brawn, while women, when asked, preferred an ‘ordinary’ body without the added muscle.

Shocking as it may seem, it is currently fairly standard practice for drugs companies to withhold clinical trials with negative results, allowing doctors to blindly prescribe drugs that don’t work or are even dangerous. In the United States, failing to publish clinical trials is punishable by a fine of $10,000 per day, but shockingly the fine has never actually been issued as Dr. Ben Goldacre explains in his editorial in PloS Medicine.

This is particularly unbelievable given that a recent study found that more than half of the clinical trials registered on clinicaltrials.gov within a given time period were never actually published (within the time period allowed by law). An earlier study, which found similar results, also demonstrated that even when the results are published, negative side effects and even serious adverse events are routinely missed out of the published version.

For an example of lawsuits that do happen when organizations don’t regulate and/or enforce misbehavior, look at my new favorite punching bag: police!

They get sued. A lot. They use fancy analytics to track and predict crime, and all the big data money can buy. But they apparently don’t turn their crystal ball inwards. Their own problems are a complete mystery to them:

For one study, Schwartz asked 140 law-enforcement agencies — including 70 of the biggest ones — for information about police-misconduct cases. A common answer: We don’t know.

So, she asked the law departments, everybody. Which didn’t always help.

“Eighteen of the largest cities and counties,” she says, “and these are cities that include San Diego, New Orleans – counties like Harris County, Baltimore County – they reported that they had no records in any government agency or office reflecting how much they spent in lawsuits involving the police.”

Be sure to click through to the study for the explanation of how just a few cops get sued over and over but face no discipline despite costing taxpayers millions of dollars in civil lawsuit settlements. Thrilling!

Which in turn reminds me of the lack of institutional awareness around medical malpractice; the doctors who get repeatedly sued for malpractice completely misapprehend the reasons that they get sued.

The refrain in all three of those links is that you cannot manage what you cannot measure. The Food and Drug Administration is apparently not managing the mass abuse of clinical drug trials, which suggests they don’t keep track of companies. The police (and their attorneys) are not measuring how often they get sued, and so lawsuits about. Physicians aren’t managing their risks of malpractice because they don’t know why they get sued, which suggests a failure to … write it down and measure it.

Oh, and here’s a fourth one that deals with poor kids if you really want your heartstrings tugged upon.

All the data (on the internal flash drive) is encrypted with a random AES key that nobody, not even the NSA, can crack. This random AES key is stored on the crypto-chip. Thus, if your phone is stolen, the robbers cannot steal the data from it – as long as your phone is locked properly. To unlock your phone, you type in a 4 digit passcode. This passcode gets sent to the crypto-chip, which verifies the code, then gives you the AES key needed to decrypt the flash drive. This is all invisible, of course, but that’s what’s going on underneath the scenes. Since the NSA can’t crack the AES key on the flash drive, they must instead get it from the crypto-chip.

Thus, unlocking the phone means guessing your 4 digit PIN. This seems easy. After all, it’s only 4 digits. However, offline cracking is impossible. The only way to unlock the phone is to send guesses to the crypto-chip (a form of online cracking). This can be done over the USB port, so they (the NSA) don’t need to sit there trying to type every possible combination – they can simply write a little script to send commands over USB.

To make this more difficult, the crypto-chip will slow things down. After 6 failed guesses, the iPhone temporarily disables itself for 1-minute. Thus, it’ll take the NSA a week (6.9 days), trying all 10,000 combinations, once per minute.

I really enjoy the Errata guys’ walkthroughs of these kinds of topics. This one is a little scarier than most, as the tools that the NSA and law enforcement use are readily available to the sufficiently motivated.

The number one cause of bankruptcy in America is medical bills. It’s been this way for a while, although that may be changing slowly. Frankly, it’s a little ridiculous when the rest of the developed world has solved the problem. Progress is progress, though.

Here’s a really great example of how medical bills get to be so bad for so many Americans. Researchers at Johns Hopkins have named the fifty hospitals in America where uninsured folks pay ten times the list price for services.

Now, sure, you’re allowed to make a profit. That’s all well and good; but a 90% markup is something out of the Apple playbook. It’s one thing to markup a luxury cell phone for people who insist on buying one. It’s another thing to mark up the treatment of an inflamed appendix for people who couldn’t afford insurance.

From the article:

“They are price-gouging because they can,” said Gerard Anderson, a professor at Johns Hopkins Bloomberg School of Public Health, co-author of the study in Health Affairs. “They are marking up the prices because no one is telling them they can’t.”

He added: “These are the hospitals that have the highest markup of all 5,000 hospitals in the United States. This means, when it costs the hospital $100, they are going to charge you, on average, $1,000.”

Okay, that sounds bad. But come on. Everyone knows insurance is a good thing. With Obamacare, you actually pay extra in taxes if you don’t have insurance. So really, isn’t it just the corner-cutters who get screwed by this practice?

Well, no.

The researchers said other consumers who could face those high charges are patients whose hospitals are not in their insurance company’s preferred network of providers, patients using workers’ compensation and those covered by automobile insurance policies.

Carepoint Health-Bayonne Medical Center in Bayonne, N.J., for example, also charges rates 12.6 times the actual cost of patient care. […] By comparison, the researchers said, a typical U.S. hospital charges 3.4 times the cost of patient care.

As usual, the article gets a quote from hospital spokespersons, who say that yes, they have “set” prices for each procedure, but nobody actually pays the listed price. Insurance companies negotiate bulk discounts for their customers, and the uninsured get to bargain down to less-obscene prices. This isn’t price gouging, it’s just imaginary price gouging.

Look. In law school, we were taught how to bill our friends and family for legal work. Always make up a crazy hourly rate, put that on the invoice, but then discount it down to your actual rate that you can actually bill your friends with a straight face. It’s a little dishonest to make up a fake price and a fake discount to arrive at a “bargain” price you wanted to charge to begin with.

But, you know. Lawyers. Sociopathy is kind of expected.

In our case, the deception was to avoid putting strain on social relationships by haggling over the price of legal services. It’s a passive-aggressive power play to your friends and family.

In this case, the deception seems to be… to frighten the unwell and uninsured (and the out-of-network and the underinsured etc.) into submission, by showing them an imaginary price they can’t afford next to a smaller price that will probably be the reason they’re bankrupt.

Another day, another bleeding heart hippie in New York City pretending that Stopping and Frisking youths doesn’t prevent crime. Get real, man! It’s scientific fact. It’s us versus them, and cops need to be forced to stop and frisk hundreds of thousands of kids a year or we’ll slip into an age of lawlessness the likes of which you can’t imagine.

“Let’s get over this issue of stop-question-and-frisk, how impactful it is, or isn’t,” Bratton said in a press conference at NYPD headquarters this morning. He pointed to 2011 as proof. That year, the city recorded 685,000 stop-and-frisks, the most ever. And, Bratton said, “In that year, rapes, robberies, assaults, burglaries, grand larcenies were all up—the year that we did the most stop-questions-and-frisks.”

Last year, Bratton said, police officers conducted approximately 48,000 stops, and “murders, rapes, robberies, assaults, burglaries, grand larcenies, were all down. So, the year we had the highest number of stop-question-and-frisks, which so many are clamoring to go back to, we actually had more crime and less of a reduction. Last year, when we had the lowest number of stop-question-and-frisks, we had much less crime.”

All right, this Bratton guy clearly has his head in the clouds. Who is he? Where does he get off making up nonsense like this? Why, I ought to-

New York Police Department commissioner Bill Bratton, responding to a call from some police union leaders to conduct more stop-and-frisks amid an uptick in violent incidents…

Oh. Well, then.

Seriously, though, Stop and Frisk is unrelated to the amount of crime in New York City, and it’s refreshing and A Good Thing that the police commissioner says things like this. What’s more interesting to me is police union leaders calling for more Stops and Frisks to combat crime. (Which they pretend is rising, but is still falling at roughly the same rate it has been for decades) I’m not sure how public and contentious that disagreement is going to get.
